One initial concern we had was that this mistrust metric might have actually been more similar to a severity score like OASIS than intended. Certainly, high-risk patients are treated differently than the general population. To dispel this concern, we compared the pairwise correlations between the mistrust score, OASIS, and SAPS II – another severity measure [1]}. Table REF  shows that the two well-established acuity scores, OASIS and SAPS II, have a strong correlation of 0.68. On the other hand, the mistrust score does not seem to simply recapitulating severity of illness, as indicated by its weak (0.095 and 0.045) correlations with the other two scores.
